From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

A solar flare ejected from the Sun shot magnetically charged particles and plasma from the Sun’s atmosphere on Wednesday, which was expected to reach earth late on Thursday.
Sever solar storms can cause disruption to power grids and satellite services, however the most notable effect is typically an increase in intensity for the northern lights.
The Met Office’s Space Weather Forecast warned of a “moderate class flare” over the last 24 hours that could lead to a geomagnetic storm from late Thursday to Friday.
“This flare may have produced a Coronal Mass Ejection (CME) but further analysis is required if this will effect Earth,” the UK weather agency stated in its forecast.
“Further analysis is also required for a CME which left the Sun around 7.30pm GMT on 21 December, as this may have an Earth directed component.”
The forecast was extended into Christmas Day in an update from the National Oceanic and Atmospheric Administration on Friday morning.
The Sun has been unusually active over the last week, according to the European Space Agency’s (ESA) Space Weather Network, with several active regions producing solar flares.
While none of them will likely cause much noticeable disruption on Earth, scientists have warned of a so-called solar superstorm in the coming years that could plunge the world into an “internet apocalypse”.
Such an event would interfere with the Earth’s magnetic field, which protects from charged particles emitted by the Sun, known as solar wind.
The Sun’s natural waxing and waning life cycle means that approximately once every 80-100 years, these winds ramp up to an extreme weather event.
The last major solar storms occurred in 1859 and 1921, causing massive damage to the telegraph network at the time.
Global reliance on technology in the years since means the next major storm could cause far more disruption, with a study earlier this year warning that the robustness of undersea internet cables to such space weather events has not been tested.
